Question:
Give a brief description of a karyotype and explain why it has such utility in diagnosing genetic disorders. What type of cells are used for deriving the chromosomes?
Answer:
A karyotype is an image showing a person's chromosomes arranged by size and shape. It helps identify genetic disorders by revealing extra, missing, or altered chromosomes. White blood cells are typically used to obtain the chromosomes.
Question:
